All a very pretty names! Camille is definitely my favorite, and I also like Solene a lot. I think Ximena is really pretty too, but I think whether you use it should depend on if you care about other people pronouncing it right. When one of my friends had an exchange student named Ximena, no one knew how to pronounce it unless she repeated it a thousand times--most people said Zih-MEE-nuh.
